Extreme close-up of restored and polished original General Electric Multiplex control knobs and faceplate.

The fine details of ‘Angus.’ This macro shot highlights the original General Electric Multiplex faceplate and knobs, hand-polished to their original 1960s luster. Beyond the aesthetics, these controls have been internally serviced to ensure modern reliability and smooth operation. This attention to detail is what defines a Steiner Audio restoration: we don’t just paint the outside; we obsess over every touchpoint of the user experience.
